Abstract
The scanning apparatus includes a control unit that controls an emission state of a light source to perform switching between first and a second emission states, wherein as a signal according to a light amount, an output unit outputs a first value when light received by the output unit has a first light amount and outputs a second value when the light received by the output unit has a second light amount larger than the first light amount, and the control unit performs switching from the first emission state to the second emission state when an output time period of a signal of the second value corresponding to the second light amount is equal to or more than a predetermined time period.
